“…As the patients in our sample did not exhibit a high degree of muscle atrophy, this increase was not observed. Normal weight distribution for the stance analyzer is the same as for a pressure-sensitive walkway-30/30/20/20 (left thoracic limb/right thoracic limb/ left pelvic limb/right pelvic limb) [45,46]. It has been proposed that bodyweight distribution at a stance may be an equivalent or superior measurement of pain associated with hip OA than both VI and PVF [33,47], and dogs presenting with the disease often have slightly abducted pelvic limbs, easily noticeable when the animal is standing, increasing acetabular coverage [10].…”

Objective This study aimed to compare the symmetry of clinical and radiographic signs of right and left pelvic limbs of dogs with bilateral hip osteoarthritis (OA) and evaluate the association of physical findings and radiographic abnormalities. Patients and methods One hundred pelvic limbs of police working dogs with bilateral hip OA were evaluated, following a screening program. Weight distribution, joint range of motion at flexion and extension, thigh girth, and radiographic signs were recorded and compared with the results of the contralateral limb and by breed, age, and sex with the Paired Samples T-Test and Pearson correlation coefficient, with p<0.05. Results The sample mean age was 6.5±2.2 years, and the bodyweight of 26.7±5.3kg. No significant differences were observed when comparing weight distribution, joint range of motion, and thigh girth of left and right limbs. Weight distribution and age showed a statistically significant correlation with joint extension. The right limbs showed a significantly higher frequency of circumferential femoral head osteophyte (CFHO) regarding radiographic signs. Limbs with CFHO or caudolateral curvilinear osteophyte had significantly larger joint flexion angle (p = 0.02) and smaller extension angle (p<0.01), respectively, compared to those that did not. Age showed a significant correlation with the presence of several radiographic findings, as did different breeds. Conclusion Clinical and radiographic signs occur symmetrically in naturally occurring hip OA in police working dogs. Several correlations were observed between the evaluations performed and differences between breeds, which can be useful in assessing and early diagnosis of hip OA.

“…Normal weight distribution on the weight distribution plate is the same as for pressure-sensitive walkway total pressure index—30/30/20/20 (left thoracic limb/right thoracic limb/left pelvic limb/right pelvic limb) [ 49 , 50 ]. For the evolution of hip OA, bodyweight distribution at a stance may even be a superior measurement to VI and PVF since dogs present different standing postures to increase acetabular coverage.…”

Background Osteoarthritis (OA) is the most commonly diagnosed joint disease in veterinary medicine, with at least 80% of the cases of lameness and joint diseases in companion animals being classified as OA. Sporting and working animals are more predisposed to develop OA since they are exposed to chronic fatigue injuries, leading to bone and muscular tissue damage and failure, resulting in clinical signs. To characterize the clinical signs and diagnostic findings of Police working dogs presenting with bilateral hip OA at the time of diagnosis. Fifty animals were evaluated with a bodyweight ≥ 15 kg, be older than two years, and without any medication or nutritional supplements for ≥ 6 weeks. Results Weight distribution, joint range of motion at flexion and extension, thigh girth, digital thermography, and radiographic signs were collected. Data from different Clinical Metrology Instruments (CMI) were collected: Canine Brief Pain Inventory, Liverpool Osteoarthritis in Dogs, Canine Orthopedic Index, and the Hudson Visual Analogue Scale. Results were compared by breed, age, sex, and Orthopaedic Foundation for Animals hip grades with the Independent Samples T-Test, ANOVA followed by a Bonferroni post hoc test, and Pearson correlation coefficient, with p < 0.05. The sample included 30 males and 20 females, with a mean age of 6.5 ± 2.4 years and a bodyweight of 26.7 ± 5.2 kg. Animals with weight distribution below normal levels had significant variations of joint extension and function scores. This evaluation was the only not correlated with at least one breed. Animals with caudolateral curvilinear osteophyte showed a poorer clinical presentation and worse scores in all considered CMIs. Radiographic changes correlated with age and corresponded to worse CMIs scores and weight distribution. Dutch Shepherd Dogs showed better CMI scores than the other considered breeds. Conclusions Police working dogs presented with complaints related to hip OA at an early stage of the disease. Hip scores influenced clinical presentation, with moderate cases showing lower thigh girth and worse pain interference and severity, and function scores than mild cases. Patients with severe OA had lower thermographic evaluations than patients with moderate OA. Age was the primary variable influencing considered CMI scores.

“…We selected a weight distribution platform in the current study since amputee patients may not be able to reliably ambulate at the required velocity to obtain valid trials on force plate or pressure sensitive walkways. In addition, weight distribution platforms are less costly than force plate and pressures sensitive walkways, require less space, and require fewer skills during data acquisition [13][14][15]. We accepted the hypothesis that Amp TPLO carry more weight on their operated limb compared to 4L TPLO .…”

Background: Little is known about the weight distribution to the remaining limbs for amputee dogs that undergo orthopedic surgery. The objective of the paper was to describe stance and weight distribution after tibial plateau leveling osteotomy (TPLO) in forelimb and in hind limb amputees (Amp TPLO) and to compare them to four-legged TPLO patients (4L TPLO) and amputees without TPLO (Amp). Weight bearing distribution at a stance was compared between groups. Joint angles of forelimb and hind limb joints in a sagittal plane, hind limb orientation in a frontal plane, and pelvic orientation in a transverse plane (pelvic tilt) were measured and compared between groups. Results: Joint angles, hind limb abduction, and pelvic tilt of Amp TPLO and Amp did not differ statistically. Mean weight bearing in the operated hind limb was higher for Amp TPLO than 4L TPLO. Mean weight bearing for thoracic limbs of Amp TPLO and 4L TPLO did not differ statistically. Weight bearing of the hind limb of Amp TPLO and Amp did not differ statistically. Conclusions: The position of the center of mass and posture of Amp TPLO and Amp does not differ. The weight distribution and posture of Amp is not impacted negatively by TPLO.

Repeatability and accuracy testing of a weight distribution platform and comparison to a pressure sensitive walkway to assess static weight distribution

Abstract: The weight distribution platform is a repeatable and accessible device to measure static weight distribution, and if proven the same in a clinical setting, it will be a valuable addition to current objective measures of limb use.
